Linhof Super Technika servicing

I'm looking into LF cameras.

I'm not sure which I'd pursue but the Super Technika IV and V are on my list.

1. How easy is it to get one of these serviced? What about bellows? What is the rough cost? I know that Leica's and Rollei's for instance are easy to get serviced (maybe not cheap...) and there are many options but I have no idea how it works for these cameras.

2. How easy is it to get one of these things cammed? I belive that the IV needs to have a matching lens/body but the V is interchangeable. How much does it cost to cam a lens?

I haven't had it done for a few years, but as I recall, it's around $350 to have a lens cammed, but really, if you haven't had the camera serviced, you'll want to send it in at the same time to have the rangefinder and groundglass calibrated, and there may be other parts needing replacement, so the cost of having a lens cammed can become part of a larger package.

1. If my lens is cammed then is adjusting the rangefinder, incase it is uncalibrated, a DIY job?

2. Can I get a viewfinder for other focal lengths? Are they easy to come by?

3. Just to be sure (as I've never owned a LF camera), I can swap out the lens board to put on an uncammed 210mm lens, then when I put on a cammed 150mm lens everything will work just fine. That is, the rangefinder will still be aligned. Silly question, but I wanted to make sure.

I'm thinking about getting a Linhof IV/V with a cammed 150mm lens, then adding a longer lens (210mm, maybe) for portraits. The tele, I think would be less useful with the rangefinder for my application so possibly postponing or not even getting it cammed.

Agree with the above, wipe off the salt spray, and lubricate the rails etc and all will be good. Mine is in need of a new bellows though, only shows up when using long lenses. I only have one lens cammed which doesn't bother me as I always use the ground glass.
